Oil prices up on OPEC warning...or is it Republican retaliation?

Oil prices rose today after the US government reported that gasoline inventories had fallen for the fifth straight week and OPEC's president warned that the group may decide to further reduce output. The Organization of Petroleum Exporting Countries last month announced its intention to cut production by 1.2 million barrels a day - 4 percent of its output - to shore up falling oil prices. Gee, and I thought it was George Bush's fault.
